Everyone knows about greenhouses, but keeping the greenhouses warm has always been a problem that plagues many growers. How do greenhouses keep warm?
In winter, there are often rapid cooling phenomena, so it is necessary to do a good job of temporary heating of the greenhouse. You can add a few heating fans in the shed to temporarily heat up in a low temperature place, but pay attention to the high humidity in the shed to prevent electrical leakage from causing bad accidents; if there are available near the shed, such as wineries, bathrooms, etc. Hot air can be fully utilized; covering the shed with straw felt is a relatively backward method of heat preservation. It is important to pay attention to regular ventilation and sufficient light every day.
Because the thermal insulation effect of the greenhouse works in winter, a cold protection system can be installed outside the shed, which is very beneficial to the thermal insulation in the shed. You can erect wind barriers, dig cold trenches, strengthen soil, thicken insulation films, etc. Everyone should pay attention to ensuring the time and intensity of light. Adequate light can ensure the photosynthesis of plants and increase the temperature in the shed.
Of course, in addition to the above thermal insulation measures, how to use the facilities and skills to achieve the purpose of insulation in the shed is also very important. The principle is to protect the temperature and heat in the vegetable shed from losing and add light to increase the heat. Fluorescent lights are installed in the greenhouse to extend the light time and collect the heat from the outside light to ensure that the heat around the plants is not lost. Use thick curtains in the shed to maintain the temperature in the shed.
